24 Identical numbers mean full digital compatibility.
4..0 FCLKTRIM (Reset default: OTP)
0…31: Lowest to highest clock frequency. Check at
charge pump output. The frequency span is not
guaranteed, but it is tested, that tuning to 12MHz
internal clock is possible. The devices come preset to
12MHz clock frequency by OTP programming.
